In the clip above, Miller performs the track from his latest work, Swimming, and YouTube commenters immediately bemoaned how significant a loss like Miller's was to the entertainment world.

"I don’t think people understood how musically talented you were champ. Your ear was ridiculous from a young age," one wrote, while another noted "Words can’t explain how I feel, I loved his music more than anything. Anybody who knows me in my small town knows how much I appreciated him. I was planing to see him again for my 20th birthday with my friends, on November 24 in Pittsburgh. I cried and cried when I heard the news."

Miller was found unresponsive at his San Fernando Valley home on September 7. He'd spoken up about his struggles with substance abuse not long before his death in a profile for Vulture.

"I used to rap super openly about really dark s---,” he said, “Because that’s what I was experiencing at the time. That’s fine, that’s good, that’s life. It should be all the emotions.
